Keitai Kaitsuu Tamagotchi Plus

Hey there! I'm Professor Zatchi.
In this guide I'll teach you everything there is to know about the second version of the Tamagotchi Plus series, the Shuku Keitai Kaitsuu! Tamagotchi Plus.
I'll use the term "Keitama" when I'm talking about the regular version and "Akai" when I'm talking about the red-screen variant.
I'll say "Keitai" or "Keitai series" when referring to both versions.

This guide is divided in parts, most of them corresponding to a care icon.
You can use the image below to go to each of the different sections. Press a care icon to learn about it, or press the character to see the character list.
If it's your first time using this kind of Tamagotchi, you may want to start with the basics. Press the buttons to go to that section.
You can use the drop-down list below instead of the image to browse the guide. Just choose a section and press the "Go!" button.
